the grouped elements will be holding the active css class only one at the time. (good for dropdowns, accordions..)

         <ul class="sub-menu" id="sub-menu-1">
            <li><a href="#">Sub-item 1</a></li>
            <li><a href="#">Sub-item 2</a></li>
            <li><a href="#">Sub-item 3</a></li>
         </ul>
      </li>
      <li>
   		<a href="#" data-toggler-target="#sub-menu-2" data-toggler-group="navigation">Item 2</a>
   		<ul class="sub-menu" id="sub-menu-2">
            <li><a href="#">Sub-item 1</a></li>
            <li><a href="#">Sub-item 2</a></li>
            <li><a href="#">Sub-item 3</a></li>
         </ul>
   	</li>
   </ul>

      <a class="btn btn-blue" href="#" data-toggler-target="#section-2, #section-3">Blue</a>
   </p>
   <div class="row">

         <div class="card red">
            <h2>Red</h2>

         </div>
      </div>
   </div>

Chaining classes

   <p>
      <a href="#" class="btn btn-blue" data-toggler-target="#my-button" data-toggler-class="btn, btn-blue">Toggle classes</a>
   </p>
   <p>
      <a href="#" id="my-button">My button</a>
   </p>

Remove Class by a group name

Great for closing menus, dropdowns etc.. on a custom event.

Imagine the following scenario: You opened a navigation via the classtoggler. Without closing it, you start interacting with the content. F.ex. you clicked on a button somewhere in the text. You expect the menu to get closed automaticaly.

   <ul>
      <li>
         <a href="#" data-toggler-target="#sub-menu-1" data-toggler-group="navigation">Item 1</a>
         <ul class="sub-menu" id="sub-menu-1">
            <li><a href="#">Sub-item 1</a></li>
            <li><a href="#">Sub-item 2</a></li>
            <li><a href="#">Sub-item 3</a></li>
         </ul>
      </li>
      <li>
         <a href="#" data-toggler-target="#sub-menu-2" data-toggler-group="navigation">Item 2</a>
         <ul class="sub-menu" id="sub-menu-2">
            <li><a href="#">Sub-item 1</a></li>
            <li><a href="#">Sub-item 2</a></li>
            <li><a href="#">Sub-item 3</a></li>
         </ul>
      </li>
   </ul>

   classtogglerRemoveClassByGroup('navigation');

Update the classtoggler after dynamic elements were added to the DOM

   classtogglerUpdate();
